NOSzle or NX Direct Port under the injectors...
Holley/NOS offers the NOSzle which fits directly under the injector. NX has a smiliar style... Are these any good? It does make installation easy. However, it seems to move the injector away from the valve... I wonder how that affects daily driving. What did you hear about this type of system.

I have seen a few tests of the NOS system,the NX setup is out for 4 bangers for now.
I saw the NOSzle being used on a PRO 5.0 car,and the results were amazing. They dyno'd before and after the install,and noticed minimal if no loss what so ever.
The NOS setup works good from what i have seen,moving the injector away isnt a big deal. The biggest problem for the LT1 is the fact that the rails have solid tubes connecting them (crossover tube 94-97),and that will not let the NOSzle be a direct fit.
You will have to modify the crossover tubes so the rails can be moved up and in towards the center of the intake.
